Brains from TSC … WebDysplastic neurons are a major contributor to epileptiform discharges in the FCD network. For example, dysplastic neurons within the lesion or in vitro reveal increased calcium influx and calcium currents upon stimulation, compared to normal neurons under the same conditions . The morphology of dysplastic neurons also contributes to aberrant ...

WebCytomegalic dysmorphic neurons (DNs; Andre et al., 2004) within FCD are distinct from BCs in that they extend dendrites and axons and are morphologically similar to neurons. In contrast, BCs are larger than DNs (often exceeding 130 microns), exhibit a laterally displaced nucleus, and lack their neuronal morphology. WebMay 1, 2016 · Depdc5 +/− rats displayed cortical cytomegalic dysmorphic neurons and balloon-like cells strongly expressing phosphorylated rpS6, indicative of mTORC1 upregulation, and not observed after prenatal rapamycin treatment. These neuropathological abnormalities are reminiscent of the hallmark brain pathology of human focal cortical …
WebIn many cases, layer I remains hypocellular and distinct from deeper laminae, but lower cortical layers may be ill-defined or broken up by the presence of many large and randomly located abnormal and cytomegalic neurons; depending on their morphology, referred to as "giant neurons," "immature neurons," or "dysmorphic neurons." WebBalloon-like cells and cytomegalic dysmorphic neurons were never observed in Depdc5 +/+ littermates. To confirm a difference in neuronal cell size, we measured the soma ... View in full-text
